A model for large-scale volcanic plumes on Io: Implications for eruption rates and interactions between magmas and near-surface volatiles. [PDF]

, 2002
Volcanic plumes deposit magmatic pyroclasts and SO2 frost on the surface of Io. We model the plume activity detected by Galileo at the Pillan and Pele sites from 1996 to 1997 assuming that magmatic eruptions incorporate liquid SO2 from near-surface ...

Upwellings and Mantle Ponding Zones in the Lower Mantle Transition Zone (660–1000 km)

Geosciences
Convective instabilities at various boundary layers in the earth’s mantle—including the core–mantle boundary, mantle transition zone and lithosphere-asthenosphere boundary— result in upwellings (mantle plumes) and downwellings (subducting slabs).

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950

Gender &History, EarlyView.
ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Mantle heterogeneity during the formation of the North Atlantic Igneous Province: Constraints from trace element and Sr-Nd-Os-O isotope systematics of Baffin Island picrites [PDF]

, 2004
Sr-Nd-Os-O isotope and major and trace element data from ~62 Ma picrites from Baffin Island constrain the composition of mantle sources sampled at the inception of North Atlantic Igneous Province (NAIP) magmatism.

Research progress of mantle plume

地震科学进展, 2021
Since the mantle plume hypothesis was proposed，it has been controversial in academia，and there is no unified answer to its existence. In this paper，the origin of the mantle plume is elaborated in detail.

Are Mantle Plumes Periodic? [PDF]

Eos, Transactions American Geophysical Union, 2013
In the past few years, researchers have uncovered evidence that several kinds of geological and biological events seem to show regular cycles of similar lengths. For example, Rohde and Muller [2005] looked at the record of diversity of marine organisms over the past 540 million years and found evidence for two cycles in the data—a roughly 62‐million ...

On Being Receptive: Listening and Compliance on a University Campus

American Anthropologist, EarlyView.
ABSTRACT How should you listen when you hear about harms in interpersonal life, such as sexual harassment or anti‐Black racism? Across a range of sites on a university campus, from bystander intervention workshops to reporting systems for sex‐ and gender‐based misconduct, we spotlight the way “listening” is mobilized to address harms of various kinds ...

Large volcanic eruptions are mostly sourced above mobile basal mantle structures

Communications Earth & Environment
Most deep mantle plumes rise from hot basal mantle structures, creating large volcanic eruptions at Earth’s surface. In previous studies, mantle plumes were the implicit process connecting volcanic eruptions to hot basal mantle structures.
